Now i know this is probably a basic question so please forgive me. i have a problem y = tan(pi*x) + 2iv established my points as x = -3pi/2 -pi/2 -pi/4 0 pi/4 pi/2 and 3pi/4 the problem is I don't quite grasp what would happen to my x points when i multiply them by pi an explanation would be great and thanks in advance for your help i can pretty much figure it out from there once i know what that initial pi*x is

That's what they show in the link the other poster gave you. They've got pictures there, too! Please do take a look; it's probably quicker (and a lot easier to understand!) than us trying to put it into words.

Yes I read the link completely the problem I am having is that it doesn't tell me what the pi does on the inside to the variables. I understand everything about graphing it and all i just don't know what the pi next to x does to each value

Yes it does: the multiplier inside (on the variable) is the "B" that tells you the length of the period. In this case, since B = pi, then the period (2pi)/(pi) = 2. Do the axis-labelling trick they show, and there you are!
